An iPad with a holder on a tripod can work quite well.
I have a blue tooth remote and use the face me camera.
I get to see the image on the screen to get a good setup.
I use a digital Blue Mikey stereo microphone.
I use ProMovie Recorder so I can see the image as it will be recorded.
$2.95 to remove the watermark from the recordings.
Without the app you see a 4/3 image on the screen when the video will be 16/9.
